Choosing the right patio door style can genuinely transform the way you use and enjoy your home. But with so many patio door styles available — from sliding glass doors to classic French doors and folding bifold doors — it can be hard to know where to start.

This guide breaks down three of the most popular patio door options in plain, practical terms. We’ll look at how each type works, what kind of space it suits best, and what to think about before you buy.

TL;DR: which patio door is right for you?

Sliding patio doors – ideal for smaller spaces where you don’t want doors swinging in or out

French doors – a classic, elegant choice that suits a wide range of homes and openings

Bifold doors – perfect for larger openings where you want maximum connection to your outdoor space

Why your choice of patio door matters

External patio doors do more than just let you into the garden. The right door type affects:

• How much natural light enters your home
• Your property’s energy efficiency and heat loss
• Home security and peace of mind
• How you use and feel in your living space
• The overall look and kerb appeal of your property

The best patio door for your home depends on your layout, the size of your opening, and how you want to use the space.

Sliding patio doors: space-saving and stylish

Sliding patio doors are one of the most popular choices for homeowners who want large glass panels without losing floor space. Rather than swinging open, they glide horizontally along a track — making them a practical solution for patios, decking areas, and kitchen extensions.

What makes sliding doors a good choice?

• They require no swing clearance, so they work well in tighter spaces
• Large glass panels flood your interiors with natural light
• Slim sightlines keep the view of your garden unobstructed
• Available in uPVC, aluminium, and timber to suit any property style

At The Little Window Company, our aluminium sliding patio doors are supplied by industry leaders Smarts and Inotherm, offering thermally broken profiles and U-values as low as 0.9 W/m²K. That kind of thermal performance can make a real difference to your energy bills over time.

Our uPVC patio doors from Kömmerling are engineered for outstanding insulation, robust security features, and long-lasting durability — all at excellent value. For those who prefer natural materials, our premium hardwood sliding doors bring warmth and character with modern weathersealing and multi-point locking systems built in.

Best for:

• Rooms with limited space for door swing
• Kitchen extensions and garden-facing living rooms
• Homeowners who want a modern look with minimal visual obstruction

French doors: timeless appeal, practical access

French patio doors — sometimes called external French doors or double doors — are a classic choice that never really goes out of style. Two doors hinge outward (or occasionally inward) from a central point, creating a wide, welcoming opening.

External French patio doors work brilliantly on conservatories, orangeries, and rear extensions. They’re an excellent choice for homeowners who want something traditional yet functional.

What makes French doors a good choice?

• A wider opening than a single door, without the full width of a bifold
• Available in uPVC, aluminium, and timber — including beautiful hardwoods like oak and mahogany
• Can be fitted with safety glass and multi-point locking for peace of mind
• Suit both modern and period properties
• Let in plenty of fresh air and natural light when open

Our aluminium French doors from Smarts and Inotherm offer slim, elegant profiles combined with high-performance glazing. The Smarts Designer Door system features a 10-point locking system with laser cut key profile and hidden hinge protectors — meeting PAS 24 standards for security.

If you’re after something more traditional, our timber French doors are individually crafted from high-quality hardwoods or softwoods, designed to suit your property’s architecture perfectly. For those on a tighter budget, our uPVC French doors blend affordable practicality with performance.

Best for:

• Conservatories, orangeries, and rear extensions
• Homeowners who want a classic, elegant look
• Properties where you want easy access to a patio or garden without a large structural opening

Bifold doors: maximum opening, maximum impact

Bifold patio doors — also known as concertina doors or fold doors — are designed to stack neatly to one or both sides, creating a larger opening than almost any other door type. When fully open, they can effectively remove an entire wall between your home and garden.

This makes them the ideal solution for homeowners who want a genuine indoor-outdoor living experience, particularly during summer entertaining.

What makes bifold doors a good choice?

• Create the widest possible opening of all patio door styles
• Large glass panels maximise natural light year-round
• Flexible configurations to suit different wall widths and layouts
• Available in aluminium and timber, with a wide range of finishes
• Double-glazed as standard, with triple glazing available for even better energy efficiency

Choose from sleek aluminium bifolds for a contemporary feel, or opt for classic hardwood Bifolding doors for a timeless charm.

It’s worth noting that bifold doors do require adequate space for the door panels to fold and stack. Your installer will assess whether your opening is suitable. At The Little Window Company, we carry out a full consultation before any design work begins, taking into account your property’s layout, soil conditions, and any relevant building regulations.

Best for:

• Open-plan kitchen-diners and extensions
• Larger openings where you want the full garden connection
• Homeowners adding a conservatory or orangery who want a real statement feature

Which door material should you choose?

Whatever patio door type you go for, the material you choose matters just as much as the style.

uPVC patio doors – low maintenance, durable, and great value. Resistant to warping and fading. Kommerling uPVC offers outstanding thermal performance.

Aluminium patio doors – slim profiles, strong, and weather resistant. Never rust, peel, or flake. Ideal for a contemporary look.

Timber doors – naturally beautiful, excellent insulation, and completely bespoke. Choose from oak, walnut, mahogany, pine, or cedar.

FAQs: patio door styles

Which patio door style is the most secure?

All three styles — sliding, French, and bifold — can be fitted with multi-point locking systems and safety glass. Aluminium options from Smarts and Inotherm meet PAS 24 security standards. Speak to our team about the right security specification for your property.

Are bifold doors suitable for smaller homes?

Bifold doors work best with larger openings. In a smaller room, sliding or French doors are often a more practical choice. We’ll assess your space during your free consultation.

Do patio doors need to comply with building regulations?

Yes. All external doors must meet current building regulations for thermal performance and safety glazing. Our team manages this as part of every installation.

Which patio door type is the most energy efficient?

All our new patio doors are double-glazed as standard. Aluminium options with thermally broken profiles achieve U-values as low as 0.9 W/m²K, significantly reducing heat loss and lowering energy bills.

Can I add patio doors to an existing conservatory or extension?

Absolutely. New doors can be integrated into most existing structures. We’ll advise on the best patio door options for your specific setup during your consultation.

How long does installation take?

Most patio door installations are completed in one to two days, depending on the door type and any structural work required. We’ll give you a clear timeframe from the outset.
